Wildfires are complex phenomena, both in time and space, in ecosystems. The ability to understand wildfire dynamics and to predict the behaviour of the propagating fire is essential and at the same time a challenging practice. A common approach to…

Understanding the conditions when litter beds will ignite from firebrands is critical for predicting spot fire occurrence. Such research is either field- or laboratory-based, with limited analysis to compare the approaches. We examined the ability…

Indigenous land stewardship and mixed-severity fire regimes both promote landscape heterogeneity, and the relationship between them is an emerging area of research. In our study, we reconstructed the historical fire regime of Ne Sextsine, a 5900-ha…

Plantations of trees are key sources of wood products globally and are increasing in extent in many jurisdictions around the world. Plantations also can be flammable and fire prone with extensive areas of the existing plantation estate being burnt…
Year Published:
The concurrent impacts of fire suppression, climate-warming, and industrial forestry have dramatically altered the spatio-temporal patterns of fire across the globe. Pyrophilic insects are among the species most threatened by these changes due to…

Background: Peatlands are becoming more vulnerable to smouldering fires, driven by climate change and human activities.
Aims: This work explores the persistent burning, propagation, and emission of the deep peat fire.
Methods: Laboratory experiments…
Year Published:
Background: Fire models use pyrolysis data from ground samples and environments that differ from wildland conditions. Two analytical methods successfully measured oxidative pyrolysis gases in wind tunnel and field fires: Fourier transform infrared (…
Year Published:
Background: Wildfires propagate through vegetation exhibiting complex spread patterns modulated by ambient atmospheric wind turbulence. Wind gusts at the fire-front extend and intensify flames causing direct convective heating towards unburnt fuels…
Year Published:
Background: Understanding near-surface fire–atmosphere interactions at turbulence scale is fundamental for predicting fire spread behaviour.
Aims: This study aims to investigate the fire–atmosphere interaction and the accompanying energy transport…

Background
Wildfire management is increasingly shifting from firefighting to wildfire prevention aiming at disaster risk reduction. This implies fuel and landscape management and engagement with stakeholders. This transition is comparable to the…

Background
In July 2012, a lightning strike ignited the Arapaho Fire in the Laramie Mountains of Wyoming and burned approximately 39,700 ha. This high-severity fire resulted in 95% mortality of ponderosa pine (Pinus ponderosa P. & C. Lawson) at…

Background: Maximizing the effectiveness of fuel treatments at landscape scales is a key research and management need given the inability to treat all areas at risk from wildfire. We synthesized information from case studies that documented the…

Conifer forests of the western US (West) are largely fire adapted ecosystems that historically have recovered naturally in the years to decades following wildfire. As climate change alters the extent, frequency, and severity of wildfire, and causes…

This is a synthesis of the research priorities from the 2023 Selway-Bitterroot and Frank Church-River of No Return Wilderness Fire Science Workshop as identified by participants.

Vegetation structure affects the vulnerability of a forest to drought events and wildfires. Management decisions, such as thinning intensity and type of understory treatment, influence competition for water resources and amount of fuel available.…
